Just wondering...why do motorhome, trailer, 5th wheel tires blow apart so bad that they cause damage to the rv?? I've had many flats on my cars and vans over the last 43 years but never had one come apart...just pop a small hole in sidewall is the worst that ever happened. Higher pressure in rv tires the cause maybe?

I'm no expert but, I would think it's from the weight they are carrying and heat generated by the tires.
Large truck tires blow apart. I've never had a car or small truck tire explode like large truck tires.
Hopefully someone will have a beter explaination.

Probably because your car doesn't weigh 10 to 15k.

A lot of today's tire are being made in China, and the tire may not be as good as the tire that were made in the USA in the past...you know you get what you pay for!!

Car tires are generally inflated in the 28-35 psi range. My TT's tires are in the 45-50 psi range, and some larger RV tires are in the 100 lb range or even more. A high pressure tire that pops is thus going to carry a LOT more energy into that pop.

Blown many truck tires that were made in the good olde USofA. Doesn't matter where their made, when 100 pounds of compressed air per square inch finds a weak spot it will tear things apart and do lots of damage. Goodyear paid for the repairs on lots of the tractor trailer full tandem, double and single radius fenders for the company I retired from when the tires they sold us blew out.

When you have a flat on your car you KNOW it's flat immediately but with a trailer you might tow it for miles and never know it's flat until you see debris flying. People OFTEN then believe they just had a blow out when they may have had a gradual leak and just towed on until it self destructed.

While I don't have any data, I believe part of the problem is that in an RV you have no real feedback when a tire goes low, then it overheats and boom!! In a car or TV you'll get feedback with a low or flat tire darn quick. On a double axle TT a tire can be flat and you won't know it till it overheats and explodes.

So that small nail and slow leak turns into a blowout.

Couple this with the limited testing that TT must pass to be sold vs. passenger car tires and it's a recipe for problems.

That's why I have a TPMS for my trailer. Figure I'll catch a slow leak or overheated tire in time to avoid a blowout under most conditions.

1. Made in China
2. Under inflation
3. Too old. More than 6 yrs.
4. They are over weight rating.

This would get my vote.

I don't buy the argument about where they are made for a second. People that talk that talk are just parroting what they heard from another mis-informed person.
